Codex is currently in its first proof of concept iteration, codenamed Dagger. Before Katana (its forthcoming testnet release, expected before the end of 2023) we aim to deliver two additional PoC clients, Scimitar and Longsword.
- **Longsword:** Codex PoC-3 will improve upon SNARK-based remote auditing mechanism and add bandwidth incentives to the marketplace—expected end of Q3 2023.
We believe the above roadmap to be the most logical approach to building a data storage engine with stronger durability guarantees and resistance to censorship than currently offered by Codex's centralised or decentralised counterparts.
First, we must establish a mechanism through which users can initiate a contract with a storage provider to host their data. Then, we can add erasure coding, required for efficient redundancy and auditing. Next, the system will need a mechanism to prove the hosts still have data available. Finally, repairs must be incentivized. Naturally, each layer of sophistication requires testing for economic and technical feasibility.
